Abstract Undesired vibration is a common issue when dealing with manufacturing machines, especially thin structures. To decrease the external disturbance sensitivity of such systems, represented for example by machine tool quill, auxiliary cable structure attached to system. The increases system damping and decreases undesired vibrations passive or active way, depending on deployment purpose. I...

Abstract This paper discusses the dynamic characterization of a 3 spans wooden cable‐stayed footbridge newly built in Italy. The is 235 m long and consists 2‐girder deck. edge are simply supported, while mid one (about 150 long) sustained by 16 stays linked to 2 pillars. Ambient vibration tests operational modal analyses performed identify global behaviour structure 17 stable modes identified f...

Cable termination faults are problematic in electrical networks almost always. Technology has solved problems somewhat, but there are many annual reports about damaged cable terminations. For analyzing the problems, faults in two regional electricity companies are studied. At first step, damaged cable terminations are analyzed statistically and grouped according to their problems. Then, some of...

In this study, analysis of dynamic characteristics and flight vibration was performed to unmanned aerial vehicles. The model supplemented by performing a characteristic test random using manufactured dummy vehicle. For the test, bungee cable used implement free end boundary condition. Prior multiple electric shaker, predict excitation force during actual test. It judged that could be predicted ...

This study uses the wind–vehicle–bridge coupling vibration analysis method to investigate bridge stiffness problem of a large-span cable-stayed-suspension cooperative system. On basis particle-damping-spring vehicle model, TMeasy surface contact tire model is introduced, and set universal algorithm built in framework whole process iterative method. Based on Latin supercube sampling principle, r...

Abstract A cable-driven model support concept is suggested and implemented in this paper. In case, it a cable suspension balance system (CSBS), which has the advantages of low interference reduced vibration responses for effective wind tunnel tests. This designed both motion control aerodynamic load measurements. CSBS, required position or attitude test realized by eight motors, adjust length, ...
